I’ve seen some users having issues when using Cura 5. After doing some experiments myself, talking to some folks, and looking around through the help forums, it seems to me that Cura 4 profiles don’t carry over well into Cura 5. I’ve personally had the best success, and seen others with the same conclusions, when they create brand new profiles in Cura 5. The default action is for Cura 5 to import all of your Cura 4 profiles. It will work, but most users end up with ugly prints. I’ve found that Cura 5 works much better when I create brand new Cura 5 profiles and update them.
